Drop-in replacement for N38AF001A packs

This 6.0 V nickel-metal-hydride pack delivers 5000 mAh and 30.0 Wh in the exact footprint of the original N38AF001A and ESR8EE5920 modules. It targets technicians who need a direct swap for legacy power-system batteries without rewiring or firmware changes. Buyers whose equipment requires a different voltage, chemistry or connector will not be served by this unit.

Steady 6.0 V output through the full discharge curve

The cell chemistry maintains nominal voltage under continuous load rather than sagging after a brief burst, so attached electronics see stable power for the entire 30.0 Wh capacity. Over-charge, over-discharge, over-voltage and short-circuit protection circuits guard the pack during extended cycling. The one-year battery-pack rating reflects tested cycle life under sustained use, not a peak-current figure.

Cool, quiet operation with certified safety margins

Ni-MH chemistry runs at low temperature during normal charge and discharge, producing no audible fan noise because none is required. The pack carries ISO 9001, RoHS, CE, UN 38.3 and MSDS certifications, confirming compliance with international transport and substance restrictions. At 644.0 g it adds minimal mass to the host system while meeting all listed regulatory marks.

Questions about this item

Does the 6.0V Ni-MH pack run hot or draw extra power when it powers a system all day?

The 5000mAh 6.0V Ni-MH cell delivers 30.0Wh and includes overcharge, over-discharge, over-voltage and short-circuit protection to limit heat and unnecessary current draw during continuous use.

What connector or mounting hardware must I already have to install the N38AF001A ESR8EE5920 battery?

The pack measures 183.9 x 32.2 x 32.2mm and weighs 644.0g; it is a direct replacement for part numbers N38AF001A and ESR8EE5920, so the original battery compartment and wiring harness are all that is required.

Will the replacement pack work with the original charger and power-management board in my older unit?

Yes — the battery is built to the exact specifications of the original N38AF001A ESR8EE5920 pack and carries ISO9001, RoHS, CE, UN38.3 and MSDS certification for drop-in compatibility with existing charging circuitry.
